Other technologies, such as facial recognition, voice recognition and Intelligent Traffic Monitoring System, are also expected to be integrated with the city’s metro system in the near future.

Compared with traditional fare gates, the new ones have an additional screen, which allows people to travel by scanning their faces, which only takes a few seconds. In this way, Shanghai residents will be able to take the subway by scanning transportation cards, QR codes, or their faces.

Voice recognition technology enables people to book metro tickets by saying their destinations to smart ticket machines. Intelligent Traffic Monitoring System also will be installed to improve traffic regulation in the metro system.
